ECN Forum Forums Code Related Discussion NEC & other Code issues Romex in commercial buildings?

Count me as another EC from IL that hates NM. When I see NM it is almost allways installed by a non electrician. I see some homes south of here that are built with NM. Then I find out I can't just pull another switch leg or another circuit. I don't work in Chicago but I've been told that some cases the electrical boxes need to be sealed or plenum in a building.
